Output Data

The output data is produced at intervals throughout a simulation which are pre-determined by the user. There are two data files produced; for restarts and Tecplot visualisation. The restart data is written to an unformatted file and contains mesh parameters along with the current flux and conservative variable values. The Tecplot data file is written as ASCII. This file also contains flux and conservative variable values along with mesh data and local vortex identification criteria - the Q criterion. For a 10⁵ cell mesh, the restart data file is around 15MB and for a $5.12\times10^7$ cell mesh, around 8GB. The Tecplot file is at least double this size and can be larger depending upon how many checkpoints are chosen by the user.
